Purpose and Brake System Fitment

The presented caliper is specifically designed for the rear left side of the vehicle, ensuring proper distribution of braking forces and compatibility with other system components. Due to its original Mercedes origin, key design parameters such as mounting geometry, piston travel, and compatibility with the model's standard brake discs and pads are maintained.

This precise fit translates to:

• stable and repeatable brake performance under typical road conditions,
• proper cooperation with brake assist systems,
• easier installation in place of a worn or damaged caliper without the need for modifications.

Technical and Construction Characteristics

As a component from the Brake Calipers and Brackets category, this model utilizes a design adapted to the standard Mercedes W204 braking system. The appropriately selected piston diameter and guide configuration allow for even pressure of the pads against the disc, which reduces the risk of uneven wear and braking vibrations.

Key functional features of this caliper include:

• factory-standard mounting points to the steering knuckle and caliper bracket,
• compatibility with the standard brake disc diameter on the rear axle,
• a design that allows for servicing with standard repair kits.

Condition, Origin, and Benefits of Choosing a Used Caliper

The offered caliper is a used component, allowing for economical brake system repair while maintaining the original manufacturer's specifications. Choosing such a solution is particularly beneficial for vehicles used daily, where a reasonable balance between repair cost and maintaining proper brake performance is important.

Using original, used brake system components is a good choice for those who:

• want to maintain the vehicle's technical consistency with its factory configuration,
• are looking for parts with a proven origin,
• plan a repair without altering the brake system's construction.

Safe Selection of Used Brake System Components

When choosing a used brake caliper, it is important to pay attention to its compatibility with the specific vehicle version, its placement on the vehicle, and the availability of interchangeable part numbers that confirm its applicability to the given model. Proper component selection minimizes the risk of installation problems and ensures correct cooperation with other system parts.
